Mutemo Wechipiri waKirchhoff

Kunzwisisa Mutemo Wechipiri waKirchhoff

Mutemo Wechipiri waKirchhoff unoti huwandu hwekuchinja kwesimba remagetsi rakatenderedza circuit yakavharwa izero. Mutemo Wechipiri waKirchhoff wakavakirwa pamutemo wekuchengetedza simba, uyo unoti simba rinochengetedzwa.

Kuti unzwisise izvi zviri nani, fungidzira chaji yemagetsi ichifamba mu closed circuit, sezviri pamufananidzo uri kurudyi. kuchaja kwemagetsi pfuura nepakati pe kudzivirira kwemagetsi (R), simba remagetsi rinodzikira nekuti rinoshandiswa mu resistance. Kana chaji yemagetsi ikapfuura neimwe resistance yemagetsi, simba remagetsi rinodzikira zvakare nekuti rinoshandiswazve mu resistance iyoyo. Uyezve, kana chaji yemagetsi ikapfuura nemumagetsi kubva pa low potential kuenda pa high potential, simba remagetsi rinowedzera. Kana richidzokera panzvimbo yaro yekutanga, simba remagetsi zvakafanana nekare, uko shanduko musimba remagetsi riri zero. Pakushandisa mutemo wechipiri waKirchhoff padunhu remagetsi, tinoshandisa shanduko musimba remagetsi, kwete shanduko musimba remagetsi.

Dunhu rakafanana neriri pamufananidzo uri pamusoro rinogona kuongororwa uchishandisa Mutemo waOhm (V = IR) uye fomura kuramba kwakatevedzana kana kuramba kwakafananaMaseketi akaomarara akadai semufananidzo uri pazasi anogona kuongororwa uchishandisa Mutemo wekutanga waKirchhoff dhani Mutemo wechipiri waKirchhoff.

Heano mimwe mitemo yezviratidzo pakushandisa mutemo wechipiri waKirchhoff kuongorora dunhu.

Kutanga , sarudza nzira iripo panguva imwe chete, kungave newachi kana kuti newachi. Kana mhinduro iri negative, nzira chaiyo iripo panguva imwe chete inopesana neyakasarudzwa. Kana mhinduro iri positive, nzira chaiyo iripo panguva imwe chete neyakasarudzwa.

Chechipiri , kana uchipfuura nepanobva magetsi emagetsi kubva pa high potential kuenda pa low potential (+ kusvika -), pane kudzikira kwemagetsi emagetsi zvekuti magetsi emagetsi ane negative value ( Δ V = - ε ). Kusiyana neizvi, kana uchifamba kubva pa low potential kuenda pa high potential (- kusvika +), pane kuwedzera kwemagetsi emagetsi kuitira kuti magetsi emagetsi ave ne positive value ( Δ V = ε).

Chechitatu , kana uchipfuura nemumagetsi, kana denderedzwa riri munzira imwecheteyo nemagetsi, magetsi emagetsi anenge ari negative (ΔV = – IR). Kusiyana neizvi, kana denderedzwa riri munzira yakasiyana nemagetsi, magetsi emagetsi anenge ari positive (ΔV = IR).

Muenzaniso wemubvunzo wechi1:

R₁ = 200 Ω uye R₂ = 300 Ω. ε = 12 Volts. Verenga magetsi ari kuyerera mudunhu uchishandisa mutemo wechipiri waKirchhoff!

Kukurukurirana

Kutungamira kwemagetsi kuri kutenderera wachi.

– IR ₁ – IR ₂ + ε = 0

– 200 I – 300 I + 12 = 0.

– 500 I + 12 = 0

– 500 I = – 12

Ini = 12 / 500

I = 0,024 Amperes

Kana zvikaverengerwa uchishandisa mutemo weOhm uye fomura yekubatanidza resistor series:

R = R ₁ + R ₂ = 200 + 300 = 500 Ω.

Fomura yemutemo weOhm:

V = IR

I = V / R = 12 / 500 = 0,024 Amperes.

Muenzaniso wemubvunzo wechi2:

R₁ = 100 Ω, R₂ = 200 Ω, R₃ = 300 Ω, ε₁ = 9 Volts, ε₂ = 12 Volts. Verenga hukuru uye divi remagetsi ari mudunhu!

Kukurukurirana

Sarudza divi remagetsi uye divi rerobho rakafanana nedivi rekutenderera kwewachi.

– IR ₁ – IR ₂ – ε ₁ – IR ₃ + ε ₂ = 0

– 100 I – 200 I – 9 – 300 I + 12 = 0

– 100 I – 200 I – 300 I + 3 = 0

– 600 I + 3 = 0

– 600 I = – 3

Ini = 3 / 600

I = 0,005 Amperes

Mwenje wemagetsi une kukosha kwakanaka saka gwara rawo rakafanana negwara rakasarudzwa.

Mumubvunzo uyu pane denderedzwa rimwe chete, mumuenzaniso wemutemo waKirchhoff pane denderedzwa rine denderedzwa dzakawanda saka kuverenga kunoshandisawo mutemo wekutanga waKirchhoff uye pane mukana wekuti denderedzwa redenderedzwa rakapesana negwara remagetsi.
